NewsMask rule in hospitals may have little impact on COVID-19 transmission during Omicron wave
A study in large London hospital during first 10 months of Omicron activity suggests the real-world benefit of mask-wearing in isolation is likely to be modest, according to new research being presented at this year’s ECCMID.

NewsOmicron appears more deadly than seasonal influenza, study suggests
Adults hospitalised with the SARS-CoV-2 Omicron variant have a higher death rate than those hospitalised with seasonal influenza, even though Omicron is considered less virulent with lower case fatality rates than the delta and alpha strains, new research being presented at ECCMID suggests.

NewsResearchers reveal why viruses like SARS-CoV-2 can reinfect hosts and evade immune response
Using a tool called VirScan, Brigham investigators found that people produced shared antibody responses to certain regions of the virus, likely leading to selective pressure and new variants that can repeatedly escape detection by prior immunity.

NewsMicrobes that “eat together” may benefit from a shared immunological memory
A new study examines viruses that infect microbes in the deep sea and finds evidence that viruses interact with a far more diverse set of hosts than was previously thought.

NewsGene scissors used successfully in the laboratory against HIV-related virus
Researchers have provided initial proof of concept for a potential therapeutic approach targeting HTLV-1, a retrovirus that triggers aggressive forms of leukemia or an incurable spinal cord disease that leads to paralysis.

NewsMosquito saliva can weaken body’s defenses against deadly dengue viruses
The saliva of mosquitoes infected with dengue viruses contains a substance that thwarts the human immune system and makes it easier for people to become infected with these potentially deadly viruses, new research reveals.

NewsHuman case of tick-borne encephalitis virus acquired in the UK for first time
The first confirmed domestically-acquired case of tick-borne encephalitis virus (TBEV) has been identified in a man who was bitten by ticks in Yorkshire, and another probable human case has been detected in the Loch Earn area of Scotland.

NewsOcean warming intensifies viral outbreaks within corals
A groundbreaking three-year study has found that viruses may increase their attacks on the symbiotic algae within corals during marine heat waves.

NewsResearchers ID plant-based compound that inhibits reactivation of the HIV viral reservoir
Researchers have zeroed in on a promising compound that targets HIV reservoirs that persist in people living with HIV despite the presence of anti-HIV therapy.

NewsTeam designs molecule to disrupt SARS-CoV-2 infection mechanism
A team of scientists led by the Department of Energy’s Oak Ridge National Laboratory has designed a molecule that disrupts the infection mechanism of the SARS-CoV-2 coronavirus and could be used to develop new treatments for COVID-19 and other viral diseases.

NewsFlu can trigger a heart attack, Dutch study suggests
Individuals who are diagnosed with flu are six times more likely to have a heart attack in the week after they test positive for the virus than they are in the year before or afterwards, a Dutch study being presented at this year’s ECCMID 2023 has found.

NewsAntibiotics do not reduce risk of dying in adults hospitalised with common respiratory infections, suggests study
Most patients admitted to hospital with acute viral respiratory infections are given antibiotics. Now new research to be presented at this year’s ECCMID in Copenhagen suggests that prescribing antibiotic therapy to adults hospitalised with common viral respiratory infections such as influenza is unlikely to save lives.

NewsmNGS outperforms microbiological tests to diagnose bloodstream infections
Next-generation sequencing (mNGS) leverages genetic testing advantage to save more lives and is found to be twice as effective at identifying infection cases.

FeaturesCannabis: The new antiviral hero?
Despite its long history of use, the plant remains largely misunderstood and stigmatised in many parts of the world.

NewsA water-dampened wipe removes Covid virus from indoor surfaces
Wiping indoor surfaces with a water-dampened wipe removes greater than 80% of Covid virus, yet pre-wetting the surface with water or detergent doesn’t make much difference, a new EPA study finds.

News‘Glow-in-the-dark’ proteins could help diagnose viral diseases
Researchers have developed a sensitive diagnostic test for viral disease that analyzes viral nucleic acids in as little as 20 minutes and can be completed in one step with “glow-in-the-dark” proteins.

NewsInexpensive way to produce anti-Covid nanobodies cuts down on the llamas
Researchers have come up with a less expensive way to isolate and identify nanobodies that target various parts of the SARS-CoV-2 spike protein and are currently derived from llamas.

NewsCommon cold gives children immunity against COVID-19
Researchers have identified memory T cells in children’s blood samples taken before the pandemic that react to cells infected with SARS-CoV-2, the virus that causes COVID-19.

NewsScreening tool pinpoints phages with best potential as antibiotics
A new screening tool circumvents the difficulty of studying individual bacteriophage proteins and determining precisely how the virus wields these tools to kill their host bacteria.

NewsScientists find ancient virus genome link to autism
An international research collaboration has made new discoveries regarding autism onset in mouse models.
